CloseDose
Built by pediatric physicians

CloseDose helps families make confident, safe dosing decisions.

We created CloseDose to demystify pediatric medication dosing with tools that feel trustworthy, accessible, and easy to use—no matter the hour or the device.

Why CloseDose exists

Parents and caregivers told us that dosing over-the-counter medicines often feels overwhelming. Between varying bottle concentrations, fast-changing guidance, and countless online charts, it can be hard to know what information to trust.

CloseDose combines clinical expertise with thoughtful design so caregivers can quickly calculate accurate, age-appropriate doses and review the context behind each recommendation.
